Midnight Oil frontman Peter Garrett introduced a very special guest during Triple J's 40th birthday celebrations last week: Daniel Johns - the lead singer of Silverchair and an undoubted VOAG (Voice Of A Generation).
Johns sat at the piano and in front of 25,000 fans totally nailed Nirvana's hit "Smells Like Teen Spirit".
Watch and listen to his haunting version in what has become an already iconic rendition for Australia's young people.
